I'm not defending the store's policies and good for her for shooting that SOB. But I work for one of Wisconsin's and Minnesota's largest chain of convenience stores and their weapons policies suck. They won't even allow their employees to carry a pocket knife of any kind, even one with a small 2" blade. Even so, I carry a 4" spring-loaded Gerber and a multi-tool on my keychain. What they don't know won't hurt them.
The hell of it is, prior to going to work for that company, I carried a Glock 19 with two spare mags every day since 2011. Even with the IWB Milt Sparks holster I use, there's no way I could conceal that under the thin uniform the company provides. So I keep it in the glove box in the parking lot, which makes it pretty much useless.
The company I work for does allow it's employees to fight an attacker, especially after one of them was stabbed to death in March 2025 by some deranged customer at one of their stores in Minnesota. After that stabbing, the company added to their policies the allowable use of spraying a potent industrial cleaner in someone's face if needed.
